Attack from Mars - weird issues

[Turtle-code]

I'm running pinMAME v3.6.0-1227, with VPX 10.8.0-2058.
When playing Attack from Mars with rom afm_113b, the table doesn't look to be working properly. For example, when i start a game, some random leds are already lit that cannot be lit; like extra ball, shoot again, the cities or leds at ramps that haven't been done yet.
The table does seems to play ok-ish, however during play, more leds will turn on that should not be lit yet, like the leds at the bottom which will lite when a goal is completed. Also sometimes the launch ball button doesn't register, or when launching the ball while holding the left flipper, doesn't engage the special skill shot.
All these things are quite random so hard to troubleshoot a logfile or someting.
